Over the last year and a half, Apple has increased its efforts to clean up the App Store, removing hundreds of thousands of clone and spam applications. According to a new report from Appfigures, Apple’s crackdown on spam and clone applications led to the App Store shrinking in size for the first time ever in 2017…

The report says that the App Store ended 2017 with 2.1 million applications available to users. That number is down from 2.2 million applications at the beginning of the year.

Furthermore, Appfigures says that developers released fewer new applications in 2017 than they did in prior years. iOS developers are said to have launched 755,000 new applications in 2017 – a 29 percent drop compared to the year before.

For comparison’s sake, the Google Play Store was up overall by 30 percent, hitting 3.6 million applications. Meanwhile, developers launched 17 percent more apps in 2017 at 1.5 million releases.

As outlined by TechCrunch, there are a few things to note in terms of the App Stores apparent decrease in size during 2017. First and foremost, Apple announced in late 2016 that it would dramatically increase its efforts at “removing problematic and abandoned apps” from the App Store.

As for the apparent decrease in new applications from developers, Appfigures speculates that this could mean Apple was stricter in its enforcement of its app review guidelines, rejecting a higher percentage of submissions than it had previous years.

Finally, the continued growth of the Google Play Store shouldn’t necessarily be heralded. Appfigures notes that some a portion of the new applications that launched on Android were simply ports of applications that had long been available on iOS.

Although ~25k apps isn’t that big of a number, this does show developers are crossing the platform barrier and extending their apps beyond the original release. Again, Google Play is winning the race. More than twice as many iOS apps came to Android in 2017 than Android apps came into the App Store.
